Um...because from my perspective the biggest drawback to medFo is speed. The lenses are slower...pretty much the only time I use 35mm now is for speed. With a couple of 645 f/2's (say 55 and 140) I might be able to live without 35mm. Also, I'm a short DOF freak. tv - This message is from the Pentax-Discuss Mail List.

I paid $750 US for a 75mm f2.8 for the 67, when I could easily find a 75mm f4 for half that. So it's worth at least double to me. ;) -Aaron - This message is from the Pentax-Discuss Mail List.

I dunno if it's a freak of nature or something, but the 75mm f2.8 is smaller and lighter than the 75mm f4. Also, my 200mm f2.8 is not significantly larger or heavier than my old screwmount 200mm f4. But in both of these cases, the faster and smaller lens is considerably newer. -Aaron - This message is from the Pentax-Discuss Mail List.

I think you have to rethink this one :-) One stop initial difference is still one stop with the TC! 2.8 plus 2x TC ==> 5.6 2.0 plus 2x TC ==> 4.0 Regards, JvW -- Jan van Wijk; http://www.dfsee.com/gallery - This message is from the Pentax-Discuss Mail List.

Re: how much 1 stop worth?
Spoken like a true wedding photographer, Bruce. On the street and shooting in poor light, fast glass is good because it allows one to hand-hold the camera at a faster shutter speeds in low light. F1.4 v F2.0 is a stop, and means the difference between 1/8sec and 1/15sec, which may mean the difference between a blurred or soft image and one that's noticeably sharper. Many people point out that faster glass allows one to see and focus better, and while that's true, that's an SLR thing. With rangefinders you can be using an f/6.3 lens and see just as well to focus as with an f1.0 lens, but you won't be able to hand hold the 6.3 in many situations . And then there's the creative control. Shooting wide open, or close to it, allows for better selective focus, which may be an important consideration in some situations. And it can allow for slower film without the need for ND filters and/or high shutter speeds, which often means finer grain or, again, different or more creative possibilities. How much is a stop worth? Well, that depends. In terms of money it's a very personal thing. But if a money shot depends on having fast glass, then it could be worth almost anything you pay for it ... hundreds of dollars. As for the cost in weight and size, well, again, if you need the speed, then you put up with the size and weight. However, many - not all, maybe not even most - people who use fast glass also have slower, smaller, lighter lenses available to them in the same focal length. So, in the end, it's a very personal thing. IAC, don't negate the value of fast glass ... even 1/2 stop can have a value sometimes.

So I will search for a reasonably priced used unit, unless a job arises that will justify the costs of a new one. Kevin, Don't hold your breath. It's nearly impossible to find a K-mount 135 that's faster than f/2.5. Your choices are limited to the Soligor 135/2.0 (72mm filter), Vivitar 135/2.3 (72mm filter), possibly the Sigma XQ 135/1.8 (77 mm filter?), and Pentax SMC 135/1.8 PKA (77mm filter). They are about equally scarce, though the first three can be found for $200 to $300, when you can find them. The only way you'll find a "reasonably priced" Pentax 135/1.8 is to take advantage of some unsuspecting widow or clueless Ebay seller with a BIN price that's a fraction of its value. You might want to buy a fast screwmount. You can easily enough find a screwmount 135/1.8 Porst, CompuStar, Sigma non-XQ, or Spiratone, or even a Vivitar 135/2.3 (my favorite), for $150 to $200. I've seen just one Soligor 135/2 in screwmount. Final option: Buy a Konica body and get any third-party lens I've named for $150.

Re: how much 1 stop worth?
Roger! The bigger the glass the brighter the screen and (most importantly) the narrower the depth of field. This makes focusing s much easier, especially in dim light. The big glass is worth it's weight in gold for this alone. Regards, Bob...

I have one of these lenses and it is quite useful. but I do alot of indoor photography where flashes are not permitted so, when 135/2.8 and a 135/2.5 showed up, the cost was minimal for the extra speed. about $150.00 as they were both attached to a K1000. Now I am in search of a yet another fast lens (is'nt this the essence of the photogaphers quest) a 135/2 or 1.8 would be quite nice, but it is a substatial increase in price. So I will search for a reasonably priced used unit, unless a job arises that will justify the costs of a new one. Kind regards Kevin - This message is from the Pentax-Discuss Mail List.

I will pay as much as a couple hundred dollars for one stop on my frequently used focal lengths. More for the focusing ease than the low light shooting capability.

RE: how much 1 stop worth?
I guess, what I would care to know is what are the situations when 1 or less extra stop makes critical difference. I can understand fast tele: when you stick 2X converter on 300/2.8, 1 stop initial difference would translate into 2 stops, and I do think that's quite a bit. But what are situations where 50/1.2 is absolutely needed over 50/1.4? If you say "available light", I have hard time believing that the gain of speed, say 1/50 vs 1/40 makes difference between a shot taken and a shot missed. Does it, really? Tom, you said, you'd pay 3 times more for a 75mm normal lens, but you didn't say why. I don't intend to step on anyone's toes, just trying to figure out what I am missing.

Re: how much 1 stop worth?
> it rather depends on which stop it is, and which lens. It also depends upon when the judgement is being made: If I'm in the middle of balancing the checkbook I'd give a different answer than if I'm in a situation where I need just a smidgeon more light for a photo than I seem to have at that exact moment...
